CHAIN MAT I'OR WHEEL-TmES.

Specification of Letters Patent.

Paton ,ed Felt. 2, 1909.

Application filed. February 1a, woe. aim: No. 300,868.

Be it known that I, BURKE JUDBON Mounnocsc, a citizen of the United States, rsid ing at Granville, in the county of Washington and State of New York, have invented a new and useful Im rovemont in Chain Mats for Wheel-Tires, 0 which the following is a specification.

This invention relates to an improved tread-mat or antislipping device for pneumatic or cushioned-tired vehicle-wheels, and, has for its ohjccts to provide a cheap, simle, durable, and efficient device that may e readily attached to or detached from a tire.

A further object of the invention is to provide a device that will not become disengaged through 1 constant use and one which will not become easily tangled when being: applied to a wheel.

Still a further object of the invention is to provide a mat which will not slip cir curnfercntially upon the wlfeeh and one in which the parts composing the mat will extend diagonally across the tread from the central portion thereof, thereby preventing the said parts turning or twisting when brought into engagement with the roadwilV.

\Vith these briefly stated objects in view, the invention cmnpriscstwo parallel arranged chain members each having; at certain intervals throughout their length, cnlnrgcd links, to each of which is connected chain sections, which extend in diverging directions over and around the tread sur face of the tire. said chain motions being (f()ilil." '.l".l'l at their opposite ends by rings which lie ccl'itrally against the tread of the win-cl, and provide a firm connection at the points of imcrscmiim of the chain se tions.

The invention also comprises ertain dctails of construction which render the mat capable of ready attachment to a tire, and also certain other details and peculiar (501th hination and nrrangcn'icnt of part w ll he fully act forth in the following specification and pointed out in the claim, reference being had to the drawings, in winch,

Figure 1 is a positive vicxv of a pneumatic tirewhcel having: my improvement applied. Fig. 2 is a detail plan view of a section of the mat. Fig. 3 is an enlarged detail view showing the ends of one of the parallel members connected, and Fig. 4 is a detail view of a. tool for applying the mat to a wheel.

III-constructing a device in accordance with my invention I employ a series of chains w'iich are connected to forma mat that extends over and on! ircly around the peri )hcry of the rim of the whccl, and by re ercnce particularly to Fig. 2 of the drawing, it wil be seen, I employ two parallel arranged chain members A, that extend entirely around and rest against the side of the cushion tire. The said members are constructed of twisted link sections A", which are united by circular or oval shaped links A, and A", which are arranged at con tain intcrv'als tl'iroughout the entire length of each memhcr and at the. ends thereof. In ractice the links A, are preferably of a larger dian'rctrr than the links A To each intermediate link A is comn cd two twisted link chain sections B which extend in diverging diremtions toward the opposite mcmhcr A, and have their inner ends connected to rings E, thereby producing substantially rectangular shaped figures througl'iout the entire length of the mat. To each end link A is connected :1 single chain section 1), whose opposite ends are comicctcd to one of the rings E, so that when the ends of the parallel members are comiccte l, the rectangular shaped figures will extend throughout the entire length of the mat. In order to connect the ends of the )arallcl arranged members, I provide the links at one end with books I, of any suitable construction which are designed to he caught into the links at the opposite ends.

When my device is attached to the rim of a wheel, the parallel members lie against the side of the tire and adjacent the rim of the when], and the twisted link sections B, will extend diagonally across, the tire with the rings 1*), resting upon the central portion of the tread as shown mostcleariy in Fig, l of the drawing, and by this arrange nwnt, it will be clearly seen that the chain sections cxtepd ovcr the entire periplgery of the tire in zigzag directions from 1th rings E, which lie against and at the center of the tread portion so that a firm grip upon the road may be had and the mat prevented jfrom slipping no matter in which direction the wheel may be revolved.

In order to facilitate the attachment of the mat, I employ a tool constructed like a IOU pair of tnlipere, and having the free ends: of the :n'rn-a bent to provide hookq and the arms (:onnetrted by a threaded holt upon which opemtee 1 thuml'i-ecrew for d awing ll'ilh this tool. the ends the arm together. of the parallel members may he drawn to gethcr lg, inserting the hooked ends into the curl links uml +-.rkre\vin; up the nut to fo ce the RI'IIH tog ther when the hooks I", may be read ly Puught into the links at. the opposite enrl oi the members.

As shown in the dun-rings, the short chain sections are eonnerxterl to the large straight links of the si k? nimnlm-e, leaving the smaller straight llfllin in the members connectetl only with the twisted links of the members. Thia idea is for the purpose of preventing or decreasing: the tendency of the twisted sections buckling ior kinking while the mat is being applied to a wheel, as it is understood that these straight links will allow t1 certain amount of revolvatory movement that would not otherwise be hail, should Cneh section between the larger links be one of eontinuous twisted links.

In practice when the mat is applied to a wheel, the ends of one of the parallel members are connected, the mat is then adjusted over the tire and then by the use of the tool, the ends of the opposite member are drawn together and eonneetml which operation is exceedingly simple and requires hut a short time to adjust the mute in plow.

From the foregoing, it ill he stun T pro virle an exceedingly cheap simple. and highly etlicient device for the [JHIINFP atili d.

llnvini! thu's' fully (lehr-rihwl my invention, what I claim as new and desire to secure by Letters Patent is:-

A trend mat for tires comprising parallel arranger] mernlwiw each consisting oi'twisted link sections having straight links intermite meeting enrls 0 the wetions .anhetzin- [ldlly ar :l'lOWJl nnrl rleacrihed.
